Pull cord light switches can go high resistance, especially if you are using LED bulbs.

Thanks, it has four LED bulbs, might try a new non LED fitting. Common sense isn't very common.

Assuming you have no earth line, some bathroom fittings do have an earth line and carried through from a double pole switch, I would consider the light is not switching off and the dim is high resistance instead of off, either a new switch or remove remove the switch and check the operation in the off position my PC is slightly to the right of Genghis

Looks like you may have connected the switch incorrectly and the earth is feeding through causing the light to be dim.

In most house wiring the switch has just 2 wires (mayby an earth).

Still pulling a cord to turn the lights on, you need to get up to date with modern technology, what could possibly go wrong!

When I looked up the internet I was surprised how common this LED glowing whilst switched off was.

It's a pull, pull switch relying on an over centre spring operation, they are renown due to wear to failing to disconnect and getting stuck, the contact is made on partial oxidised metal caused by sparking on disconnect thus giving a high resistance contact, LED lamps on 240v can work to as low as 100v as they use a chip to reduce the voltage so as not to supply a high voltage to the led but really the low voltage is not considered. my PC is slightly to the right of Genghis

It worked fine to begin with so must be connected correctly Common sense isn't very common. _______________________________ 2007 Land Rover Freelander2 I6 hse Auto |

I may be new, but it's still pull,pull, even new can fail with todays suppliers, I would still suspect the switch, it worked before you went away and now it doesn't, unless you have that annoying broken wire in the insulation that is making poor contact. my PC is slightly to the right of Genghis

I've had the same issues with pull switches passing enough current to make LED lamps glow. I've had them also momentarily disconnect, then reconnect again, causing the LEDs to flick off then on again. Pull switches aren't that great IMO. Hyundai Ioniq 5 Ultimate. The family car.
